A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the ...

The present solid Earth is actually active, with new plates generating in the mid-ocean ridges and some old plates sinking back into the interior through subduction zones. Subduction is thus a key ...

RPI researchers were the first to ever collect data during an underwater eruption on the Mid Ocean Ridge System. They happened to be on site to gather data from hydrothermal vents.

Mid-ocean ridges represent regions of the planet where volcanic activity is generating fresh oceanic crust and submarine mountain chains -- known as axial volcanic ridges -- as two tectonic plates ...

Mid-ocean ridge basalts (MORBs), located far from subduction zones, are typically thought to be unaffected by subduction processes. However, some MORBs display arc-like geochemical signatures ...

The discovery of both trenches and mid-ocean ridges paved the way for geologists to accept plate tectonics by providing an ...

Enhanced spreading at the Mid-Atlantic Ocean Ridge due to ice melting from Greenland may have contributed to that fiery past—allowing more magma to rise to the surface, fueling the eruption of ...
